1 PIN JOINT FOR BROOCHES we LIKE fins.

Application filed July 15, 1927. Serial No. 206,082..

chinery, as to form a suitable type of pivot-' mg means or joint of the same stock as the plate,pre'ferably from artongue cut from the plate and thus integrally secured thereto. My invention is peculiarly applicable to plates made of this sheet metal, such as where it becomes necessary to attach the free end of said tongue to said plate to form a firm mounting for the joint for said pintongue. My invention specifically relates to the improved means and method I employ to firmly secure the free end of said tongue to the back plate when thin metal provide a firm pin tongue pivoting joint securely attached to said plate against movement in either direction, without materially increasing the number or the difficulty of the manufacturing steps.

These and suchother objects of my invention as may hereinafter appear will be best understood from a accompanying drawings which illustrate a completed embodiment thereof and diagrammatically illustrate the steps to be performed in the manufacture thereof.

In the drawings, Fig. l is a front elevation of a skeleton plate for pins, brooches and the like with my pin tongue pivoting means integrally formed therefrom and cured thereto. Fig. 2 is'a rear elevation of a plate blank with the first step in the process of manufacture of my completed article, namely, the cutting of the pin tongue hole and formation of the catch performed thereon.

Fig. 3 is a sectional view taken along the line 33 ofFig. 2. i

Fig. 4 is a rear elevation of said plate with the next step in the manufacture of my improved pin tongue pivoting joint performed thereon, namely, the cutting out of the tongue withthe locking lugs integrally projecting from each side thereoflfrom the metal of the plate. 7

preferably integrally formed fromaY plates are employed to description of the.

Fig. 5 is a sectional view line 55 of'Fig. 4.

Fig. 6 is a rear elevation of said plate after the next step in the manufacture of taken along the my invention has been performed thereon,

namely, with the in tongue pivot pin receiving loop formetl on therear thereof and the free end of the tongue drawn towards the integral end in the channel cut out in said plate. i

'Fig. Sis a rear along the elevation of the plate shown in the preceding views with the next step in the manufacture of my invention performed thereon, namely, with the pivot tongue hlade inserted through the hole in the loop and the loop further crimped around the pivot pin thereof to firmly secure it thereto and yet permit pivotal movement thereof, further drawing over the laterally projecting lugs in'the channel in opposite sides of said plate.

Fig. 9 is a sectional view line 9-9 of Fig. 8.

Fig. 10 is: a rear elevation of the completed article after the last step in the process of its manufacture has been performed thereon, namely, ly projecting lugs into the soft metal of the plate on opposite sides thereof to firmly secure said pin tongue pivoting means thereto against movement in opposite directions.

Fig. 11 is a sectional view taken along the line 1111 of Fig. 10.

In the drawings, wherein like characters of reference generally indicate like parts throughout, 15 is a suitable plate preferably formed of thin metal, preferably a copper sheet, from which my invention is to be integrally formed in a manner to be explained. My invention can probably be best explained from its method of manufacture.

The first step in the manufacture of my invention may comprise cutting the pin tongue blade pivoting hole 16 near one end thereof and cutting and striking up from the plate the pin tongue catch 18 preferably near the opposite end thereof, which steps may be either doneby hand or by suitable automatic machinery, as all the steps later to be described.

Figs. a and 5 illustrate the next step in the method of performing my invention, which taken along the comprises cutting through said plate preferthat of pressing the lateralloo sorting having ably in the direction of the catch 18 to form the free tongue 20, having one end 22 thereof integrally secured to said plate and inner and outer sets of lugs projecting laterally therefrom on each side thereof .preferably spaced from each other the length of the metal in a loop 25 to be formed, the outer lugs 26 being preferably smaller than the inner lugs 24 so that they may be readily pushed through the inner lug holes 36 in the manner later described.

The next steps in the process are illustrated in Figs. 6 and 7 and these comprise dapping the tongue toward the integral end 22 thereof to form a loop containing the hole 16 on the upper end thereof to receive the pin tongue blade pivot pin 28 of a T pin preferably integrally attached'centrally to the pivot pin blade 30. The formation of the loop 25 coincidentally draws the tongue 20 over in the cut out portion 32 from which the tongue 20 was out until the outer lugs 26 come adjacent the inner lug holes 36 with the inner lugs 24; overlapping one side of the plate 15, the rear as shown. The outer lugs 26 will come immediately adjacent the laterally extending holes 36 in the cut out portion 32 from which the larger inner lugs 21 were cut, for as stated, the inner lugs 2% were spaced from the outer lugs 26 a distance. substantially the length of the metal in a loop later to be formed.

The next step in the process comprises inthe pin tongue blade of a T pin the pin tongue pivoting pin 28 integrally attached to the base thereof through the loop 25 until the pivot pin 28 thereof is loosely contained within said loop 25 and coincidently therewith thesmaller outer lugs 26 are pushed through the inner lug holes 36 until they lie on the opposite side of said plate 15 from the inner lugs 24.

Figs. 8 and 9 illustrate the next step in the manufacture thereof, which comprises compressing in any suitable manner the loop 25 around the pivot pin 28 tight enough to closely bind said pivot pin and yet permit free pivotal movement thereof with the pin tongue blade 30 swinging within the hole 16. It is apparent that this further compression of the loop 25 further draws the tongue in said out out portion 32 toward the integral end thereof until the outer. lugs 26 overlap the opposite side of the plate 15, the front as shown in Figs. 8 and 9.

The last step of the process is illustrated in Figs. 10 and 11 and comprises compressing the inner sets of lugs 24 overlapping the rear of the plate 15 forwardly into the soft metal of said plate 15 from the rear thereof and the outer sets of lugs 26 overlapping the front side of said plate 15 rearwardly into the soft metal of the plate 15 to form surfaces on each s'de of said metal plate substantially flush therewith. As stated, in

place of forming the lugs 24: and 26 and pressingjthem into the plate as shown in Fig. 10, other suitable means, such as solder ing, etc., may be employed to secure the free end 27 of said tongue 20 to the plate 15.

It is thus obvious that when completed I have provided a suitable thin metal plate 15 for brooches and like pins, having a suitable pin tongue pivoting means or joint integrally formed thereon comprising a tongue 20 cut out from said plate having a pivot pin loop 25 projecting rearwardly from near the integral end 22 thereof adapted to enclose a pin pivotpin 28 and having a hole 16 therein of a size to permit free pivotal movement of the pin blade 36 therein and the free end 2'7 of said tongue 20 beyond said loop 25 firmly secured to said plate in the tongue channel 32 in one direction by a set of lugs 2 1 projecting integrally therefrom overlappingly pressed into one side of said plate and in the opposite direction by the lugs 26 projecting integrally laterally therefrom overlappingly pressed into the-opposite side of said plate, and I have further provided in combination with such a means, a pin tongue catch 18 spaced from said pivoting means and a pin tongue blade 30 of a T pin having the pivot pin 28 at the base thereof firmly secured within said loop 25 to permit pivotal movement thereof through said hole 16."

As stated, means such as solder, other than the lugs 2% and 26 may be provided to firmly attach the free end 27 of said tongue 20 to said plate 15 where said plate 15 is constructed out of soft metal.

It is apparent that I have provided a strong pin tongue pivoting means or joint firmly secured against movement to said plate integrally cut out and formed from the metal of the plate either by hand or by well known types of automatic machinery.

It is understood that my invention is not limited to the specific en'ibodiment shown or method described and that various devia tions may be made therefrom without departing from the spirit and scope of the appended claims.
